Welcome to Just Answer and thanks for your question. There are a lot of meanings for the acronym APA. Which one are you referring to?
The American Psychological Association is an association of psychologists. They don't dictate anything in colleges. Perhaps I am missing the point of your question?
The APA style manual is used in the behavioral and social sciences. It is a clean, clear, simple style of presentation with its own set of rules of punctuation, headings, chart structure, and citation of sources that is used world-wide.
Please see the answer above. All aspects of formal scientific writing for social and behavioral sciences is covered by APA style.
